Title: Counterpoise suspension
Inventor: BOULSOVER GEOFFREY
IPC: F16M11/04
Filed: 1954-07-01
Abstract: 785,363. Counterbalanced brackets. AMALGAMATED DENTAL CO., Ltd. July 1, 1955 [July 1, 1954], No. 19298/54. Class 52(5) A counterbalanced bracket comprises a parallelogram linkage and a spring- loaded cross link, a cam and follower mechanism being provided to vary the spring thrust in response to displacement of the linkage to give automatic counterpoise as the long links of the parallelogram are swung to both sides of the horizontal. As shown, a sleeve formed by cover plates 6 and a tubular strut 9, housed in the sleeve, form the long links of the parallelogram, the short links being formed by a plate 1, secured to a support 4 by a vertical pivot 3, and a plate 10 connected by a vertical swivel pin 11 to a support 12 for the load. The plates 6 and the bifurcated ends 8, 15 of the strut 9 are pivoted to the plates 1, 10 at 5, 13, 7, 14, the end 8 being slotted at 19 and housing a roller 20 yoked to a bearing 23 slidable on the strut 9. One end of a cross link 16 is also pivoted to the plate 1 at 5 and at its other end is pivoted at 17 to plates 6 and to a bearing 18 slidable on the strut 9. A spring 24 between the bearings 18, 23 urges the roller 20 against the end of plate 1 which is shaped as a cam 25 circular about the pivot 7 and having a sharply curved lower part 26 so that as the linkage is depressed below the horizontal the bearing 23 recedes from the bearing 18 and the thrust of the spring is diminished, diminution on the other side of the horizontal being effected by sliding of the cross-link. The cam profile is such that counterpoise of the load is effected by the change in the thrust of the spring together with the leverage of the roller 20 on the strut 9. An abutment 27 and threaded sleeve 28 are a fine adjustment and for use with an electric lamp wires and a switch are provided.

Abstract: 622,918. Friction drives. SOC. D'APPLICATIONS GENERALES D'ELECTRICITE ET DE MECANIQUE SAGEM. July 28, 1945, No. 19370. Convention date, Dec. 26, 1944. [Class 80 (ii)] [Also in Group XXVI] In a drive system wherein a single electric motor 1, the speed of which may vary, drives a number of load shafts, in some e.g. 4, of which the speed variations of the motor can be tolerated whilst in others e.g. 17, 18 the speed must be held rigorously constant, the former are driven directly (or through fixed-ratio gearing 2) whilst the latter are driven through a frictioncoupling 8 and are subject to a governorcontrolled friction brake 21, which increases the resistance and so causes increased slip in the coupling 8 when the speed exceeds the required constant speed, the motor driving the coupling 8 always at a greater speed than the required speed. The coupling comprises driven discs 10, 11, pressed by a spring 9 to grip between them a driving disc 8. The governor-brake is isochronous or nearly so, and comprises centrifugal masses 28, 29 and 30, 31 on pivoted arms 22, 23 opposed by a spring 32 and serving to move axially a brake-disc 42 in relation to a spring-pressed brake-pad 43, thus varying brake-pressure and so frictional resistance. Speed may be varied by adjusting the brake-spring 44 and isochronism by varying the relative proportions of the masses 28, 29.

Title: Flush rotary fastener
IPC: F16B5/02
Filed: 1972-04-26
Abstract: 1326869 Rotary fasteners DZUS FASTENER CO Inc 26 April 1972 [23 June 1971] 19456/72 Heading F2H A stud 21 is locked in any required position on a receiving member 22 by means of a locking device which comprises balls 29 normally forced outwards by a cam 27 fixed to a leaf spring 28, so as to engage a resilient skirt portion of the stud 21. Rotation of the stud 21 over the balls 29 causes rotation of the cam 27 against the biasing spring 28, thereby enabling further stud 21 rotation until the position required is reached. The spring 28 then tends to rotate the cam 27 back to its initial position thereby wedging the balls 29 outwardly against the skirt. Subsequent unlocking requires an initially high torque to force the balls 29 over the high points of the cam surface, deformation of the stud skirt occurring during this proceedure. Further back rotation of the stud 21 then requires a minimal torque. Two panels 31 may be fixed together using the fastener by bolting the member 22 to one panel 31 and providing an aperteur in the second panel 31 for receiving the rotatable stud 21.

Abstract: 446,413. Jack-guides on road vehicles. POWELL, G. F., 67, Mount Park Road, Ealing, and HENRY, H. D., 22, Grosvenor Road, Chiswick, both in London, and PRIMA CO., Ltd., Commercial Street, Birmingham. July 3, 1935, No. 19561 /34. [Class 79 (iii)] A laterally extending jack guide on a road vehicle comprises a rod of circular or substantially circular cross-section which enables the jack to be tilted sideways if necessary to clear obstructions whilst being slid thereon into its operative position. The guide rod c, which may be horizontal or bent downwards under the running board d, is carried by an angle member a secured under the chassis longitudinal b. The slot e provides clearance so that the head f bears against the frame member when in position, the head being flat or shaped to conform to a recess in the under-surface of the angle member a to prevent tilting when in position. The slot may be at the side of the head as shown in Fig. 4. A spring catch may sustain the jack body from dropping whilst being slid along the guide rod and a pointer or gauge strip may be carried by the jack to contact or register with the edge of the running board when the jack reaches its operative position.

Filed: 1932-07-12
Abstract: 383,592. Geographical universal clocks.. HEIMANN, E., 20A, Toegoe, Djokja, Java, Dutch East Indies. July 12, 1932, No. 19662. Convention date, Sept. 16, 1931. [Class 139.] A geographical clock for simultaneously indicating the times of various places, has a common drum 3 with minute scales for the various places and separate hour discs 4, one for each place, which are actuated by an independent drive 11, each disc being moved one step forward as the corresponding minute scale passes through zero. The clock 1, which shows at 2 the standard time of the place at which the device is used, has four units each consisting of a minute drum and eight hour discs. Each unit has an indicator slide 5 with a finger 6 so that the time at any of the eight places may be seen by adjusting the slide; the top numeral being the hour, and the lower being the minutes. Manually adjustable discs 7 are used to indicate whether the times are earlier or later than the time shown bv dial 2. Each minute drum 3 is driven from clock 2 one revolution per hour and pins 31 on the drum rotate a starwheel 30 rigid with shaft 29 and cams 23 for the corresponding eight hour discs 4. The top hour disc 4a, Fig. 8, is rigid with a shaft 14 which is actuated by a drive 11, Fig. 2, which is independent of the clock drive 2 and is controlled by ratchet and pawl 27, 28 similar to striking mechanism. Pawl 28 is removed from wheel 27 once per hour by a pin on one of the minute drums and permits wheel 27, and the four shafts 14, to rotate a distance equivalent to one hour before it falls into the next notch of wheel 27. In each unit the seven discs 4b, additional to disc 4a, are loose on shaft 14 and have slots 16 through which pass a pin 15 rigid with disc 4a. A spring 17 anchored to each disc 4b at 18, presses on pin 15. Each disc 4b is arrested by a spring-pressed brake 20 so that when the drive 11 moves disc 4a one step, the pin 15 moves to the other ends of slots 16, stressing the springs 17. When any minute scale on drum 3 passes through zero, the corresponding cam 23 momentarily removes its brake 20 so that the corresponding hour disc 4 is moved one step by its stressed spring 17.

Abstract: 670,741. Radio direction-finding; pulse circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 6, 1950 [July 26, 1949], No. 19667/49. Classes 40 (vi) and 40 (vii). Relates to direction-finders of the type in which the D.C. voltages x and y respectively proportional to the sine and cosine of the incoming signal direction # are applied to the orthoganal deflection systems of a cathode-ray tube to produce a spot of angular position #. According to the present invention the spot is transformed into a radial line by applying the x voltage in push-pull to a pair of valves, each having negative feed-back between anode and grid and one deflection system being connected between the anodes; the y voltage is applied to a similar pair of valves and the conductivity of all four valves is periodically varied by a waveform generated by a switching valve which is periodically cut-off by a periodic voltage. The voltages x and y may be produced by applying the output from a constantly rotating goniometer to two phase discriminators together with the outputs from a two-phase generator rotating synchronously with the goniometer. In one embodiment, Fig. 1, one input D.C. voltage, e.g. y is applied in push-pull at X and Y to two pentodes VI and VII, negative feed-back resistors R2 and R21 being connected between their anodes and grids and one deflecting coil L of the cathode-ray tube being connected between the anodes so that the current through the coil L is linearly related to the potential difference between X and Y and the valves are intermittently blocked by a negative distorted square wave SW, Fig. 1a, applied in parallel to the suppressor grids so that the current through coil L is periodically varied. The other D.C. voltage x is applied to the other cathode-ray tube deflecting member through a similar circuit (not shown) so that the cathode-ray beam traces a radial line on the screen. In a modification, Fig. 2 (not shown), resistors R4, R41, capacitor C2 and bias connection - GB are omitted and the feed-back resistors R2 and R21 are replaced by capacitors so that the valves function as Miller integrators and the blocking voltage is an undistorted square wave so that the variation of potential difference between the anodes will be linear and the resultant radial trace will be of constant intensity.

Title: Control for friction clutches
IPC: F16D23/10
Filed: 1923-08-01
Abstract: 224,274. Bichteler, H., and Aktieselskabet Asra. Aug. 1, 1923. Variable-speed gearing; clutches, friction.-Rotary driving and driven members 11, 12 are connected bv a friction clutch 13 and a rotary controlling member 15 and the clutch is engaged and disengaged according as the speed of the driven member 12 is below or above that of the controlling member 15. The member 15, which is driven or allowed to rotate at a speed less than that of the driving-member by suitable means, is formed as a nut screwing upon a member 14 fast on the shaft 12. The member 15 is connected with the member 11 so as to move the latter axially when screwing takes place. When the shaft 12 and controller 15 are turning at the same speed, the screw-and-nut mechanism is turning solid. The moment the driven member overruns the controller, screwing takes place, disengaging the clutch enough to allow slip. A spring 8 effects the reverse motion. A modification is described in which the clutch is in the form of a band applied by a toothed sector and central pinion, relative turning of the pinion releasing the band. In another arrangement, shown in Fig. 5, a friction coil 36 extends from the far end of a driven drum 34 round that drum and round the driving drum 30, the end being secured to the controller, which is a toothed wheel 38. When the drum 34 overruns the controller, the coil 36 unwinds, allowing the clutch to slip. Reference has been directed by the Comptroller to Specifications 1880/82, 10318/90, 173,533, and 191,061 (as open to inspection under Sect. 91 of the Act).

Title: A method of increasing the vitamin e biological activity of -a-tocopherol
IPC: A61K31/355
Filed: 1954-07-08
Abstract: The Vitamin E activity of b -tocopherol is increased by chloromethylating it in a tocopherolcontaining phase, the hydrogen chloride normality of which is from 0.8 N to 1.0 N, and reducing the chloromethylated product.  The chloromethylation may be effected by means of formaldehyde, paraformaldehyde or dimethyl formal in conjunction with the hydrogen chloride, or by means of chloromethyl ether.  The desired hydrogen chloride normality during this step is advantageously achieved by treating the b -tocopherol in a non-aqueous organic solvent phase in contact with an aqueous acid phase, the total hydrogen chloride normality in the mixed phases being adjusted to 4-5 N, e.g. by passing in gaseous hydrogen chloride.  The reduction step may be effected by hydrogenation in the presence of Raney nickel at moderate pressures or by adding zinc dust to the acidic reaction mixture. The process is applicable especially to the treatment of compositions containing at least 50 per cent of b -tocopherol, e.g. the product obtained from a composition containing a substantial amount of d -tocopherol by converting said d -tocopherol to a mixture of b - and a -tocopherols and separating the former from the latter.  Examples describe the treatment of (1) a concentrate in which 76.5 per cent of the total tocopherol content is b -tocopherol, dissolved in diethyl ether; (2) a concentrate in which 86 per cent of the total tocopherol content is b -tocopherol, dissolved in isopropyl ether.

Abstract: 1331337 Electro-medical apparatus AMERICAN OPTICAL CORP 19 April 1971 [21 Jan 1970] 20139/71 Heading G1N Multiform VPB's, i.e. originating from different faci of the ventricle, are detected by characterising each QRS waveform as one of eight categories, e.g. as described in Patent Number 1304460, detecting the QRS waveforms resulting from a VPB, and registering the occurrence a QRS waveform of each category which resulted from a VPB. An indication is given when at least two QRS waveforms of different categories resulting from VPB's are registered. As shown, Fig.2, after each QRS waveform is detected, one of the lines +M9 to +M16 is energized to provide a high output at the respective output +9T to +16T of temporary flip-flops 9TEMP to 16TEMP until the following- RESET pulse, thereby categorising the QRS waveform. If, after the next QRS waveform has been detected, the previous waveform is determined to have been a VPB (by the generation of the +VPB pulse), the permanent flip-flop 9 PERM to 16 PERM associated with the energized temporary flip-flop is pemanently set, a high output appearing on the respective output +9P to +16P. Upon each temporary flip-flop being set respective AND gates 9G to 16G are enabled to provide a high output on +G9 to +G16 respectively. A low output is provided from gate 32 upon one of the gates 9G to 16G being enabled. However, when one of the permanent flip-flops is set the associated gate 9G to 16G is permanently disabled. Upon detection of the first VPB, a gate 35 is disabled by a flip-flop 34. However, when a VPB resulting from a QRS waveform having a different category from the first VPB detected, is detected, a low input is applied to each of the three inputs of gate 35 thereby energizing multi-form alarm 37 via flip-flop 36. A third VPB of a third category may be indicated by resetting flip-flop 36 via switch 53, and so on. Lamps L9 to L16 are provided to show which flip-flops are permanently set.
